What? Even if there are no copyright holders, the AI companies will still do scan'n'destroy because it's just cheap.
Are you expecting the authors/publishers to send digital copies to AI companies directly? Or expecting AI companies to preserve the physical copies indefinitely? Both are not gonna happen, copyrighted or not.

There is also a legal element. If they kept the physical copy around after scanning the argument is that they're making copies of the book which puts them on tricky legal ground. By destroying the physical copy they can argue that there is only one version of the book that now exists solely in digital form, so this usage is better protected under fair use.
